However, keep in mind that a factory reset will erase all your personalized settings and installed apps, so make sure to take a backup if necessary.
If the problem persists after performing a factory reset, it may be worth contacting Hisense customer support for further assistance. They can provide specific troubleshooting steps tailored to your TV model and may even be able to diagnose any software-related issues remotely.
HDMI Connection Problems: Identifying Issues With HDMI Cables And Ports That Lead To The TV’s Erratic Behavior
HDMI connection problems can be one of the causes behind your Hisense Roku TV turning on and off unexpectedly. Faulty HDMI cables or loose connections can interrupt the communication between your devices and the TV, resulting in frequent power cycling.
To address this issue, start by checking the HDMI cables for any visible damage or fraying. Replace them if necessary. Additionally, ensure that the HDMI cables are securely connected to both the TV and the external device. A loose connection can lead to intermittent power cycling.
